Our HCI/HCCI engine is projected to achieve 30% more fuel efficiency than a standard ignition engine. One of the greatest benefits of HCI/HCCI is the ability to scale the size of the cylinder chamber, radically increasing the power output of the engine with only 2 cylinders. This unique patented design solves the inherent challenges of pre-ignition, poor cold starting, unbalanced combustion, uneven temperatures, limited RPMs and loads. With the single piston projected to produce 75hp power output, the Nautilus Boxer Engine is projected to output 150hp initially. Weak torque, you say? Don't say being tailgated by another Type R or more powerful cars la.īoxer engine in 86? Can't wait to see and hear one on road or in a drift scene.We took all of the benefits of the Nautilus Cycle and put it into our Nautilus Boxer Engine. Even being tailgated, I rarely need downshifts or engaging Vtec just to prove its worthiness being a Type R. Don't forget a K20A is packed with valvetrain wizardry. The relationship between the torque and horsepower is quite 'healthy'. Being close-ratio, it shortens the shift timing and allows the engine to rev faster but in the same these gears must be able to transfer the engine's output efficiently.īack to torque talk, if not mistaken, a K20A in a DC5 is capable of producing a little above 200Nm at around 7k rpm and 220PS at 8k rpm. Track cars of course must be able to pull out from a corner fast too, hence, the reason for close-ratio box. Obviously, engines give their best performance at peak and being track cars, an ideal engine should rev quickly to its peak. Having track setup inheritances, its not exactly everyone's favorite daily driven car. With designs only for functionalities along with Helical LSD, high revolution mills, track-like suspensions, strengthen chassis, Type Rs ARE in fact track cars that have evolved into street machines. If you'd think it over, its a 2.0 engine bolted onto a considerably light chassis (not sure if FD2R can be considered light since its chassis is a passenger type). I believe its because of its subtle presence that might have led one to believe that a K20A has relatively weak torque. Hmm…I wouldn't say the modern days Type R have horrible torque at least not for a DC5. VIDEO: Toyota FT-86 Concept in Gran Turismo Toyota FT-86 Concept – AE86 spiritual successor finally previewed! It won’t surprise me if the 2.0 litre D-4S Boxer engine in the production Toyota FT-86 coupe may make over 160 to 170 horsepower and around 210 to 215Nm of torque, which exceeds what regular 2.0 litre engines with port injection can do. 377Nm of torque from a 3.5 litre engine while maintaining good emission, refinement and fuel consumption figures is not easy to get. In the 2GR-FSE 3.5 litre D-4S V6 engine, it allowed Toyota to tune the engine for very impressive torque to litre ratio figures for a normally aspirated engine. The system will pick between the two types of injectors according to needs (here’s a good story on how it works). D-4S combines both direct injection and conventional port injection for each cylinder which means two injectors per cylinder, or eight injectors if the engine is a 4-cylinder boxer like the FT-86 production car will have. D-4 is basically gasoline direct injection, and D-4S stands for D-4 Superior. You might have noticed D-4D badging on local Toyota Hilux pickups – that’s their diesel direct injection. The Subaru version of the FT-86 (if it’s still going to be produced) will also feature its own Subaru D-4S Boxer engine.ĭ-4S is basically an advanced variant of Toyota’s D-4 direct injection system. Sometime earlier this year at the Tokyo Auto Salon, Akio Toyoda said that the production car will not be coming very soon because a new boxer engine with Toyota D-4S technology was still being developed. The fact that the production version of the FT-86 coupe will feature D-4S is not new actually. We can also predict its power output based on other engines that have featured D-4S and high compression in the past, like the 2GR-FSE. Now this makes so much sense, and also gives us an idea of the kind of technology that’s going to be found in the new engine. A pretty sharp reader managed to point out that the words found on the Toyota FT-86 boxer engine is actually D-4S Boxer and not C-45 Boxer.
